✅ Building a Better Air Compressor for My Garage for DIRT CHEAP !

Lots of people suggested that I should use the second tank that I got as an expansion tank to double the amount of air being stored. That idea did cross my mind, but in my situation I just did not see the need for that. The new air pump easily out pumps the amount of air being used even if I am continuously painting. Just wanted to put it out there 😊

I have so much respect for him testing this thing for a year before posting it, it shows he cares

Okay, spinning the tank on two dolly’s strapped together is next level.

That tank rotisserie was GENIUS!

I actually loved this video. You showed the tank rehabilitation, testing, new pump system, pully calculations, pump sizing, and other considerations. This was equivalent to real mechanical engineering. Good work.

I like how you performed the pressure test behind the tree, far from your house, and closer to the neighbor's house. 🙂 Thanks for the video. I plan to build something similar.

Awesome job man! Only thing I would have added, while you were in the early stages and had the dollies hook together to make a rotisserie, I would have dried that tank out and poured in a quart or 2 of bare metal primer. You could have spun it around and flipped it up and down, coating the entire tank, and then opened up the bung on the bottom and collected the excess primer. This would have insured the tank would be rust free for many years!

Grandpa gave me his oil filled compressor when he bought a new oilless compressor. Some time later I ended up with the oilless, so I gave the oil filled compressor to my kid. Some time after that, I was at my kids house and he fired up the compressor. I miss my oil filled compressor. The sound is so much better.

I like that it has a vertical tank. Floor space is valuable for the average DIY'er.

I work on compressors for a living and I was really impressed! I wish all of our customers were as knowledgeable as you but then again I’d be out of work lol

Just as an added explanation about the oil. The reason you have to use non-detergent oil is because detergents are designed to keep contaminants suspended in the oil so they can get filtered out. In an engine without filtration you want the contaminants to fall to the bottom and stay there.

Awesome, i agree with a lot of what you did. The 2 things id change is after cleaning the tank, throw a gallon or 2 of phosphoric acid to convert any rust, basically stopping it dead in its tracks. Drain and let it dry and coat the inside of the tank with an epoxy paint. Thing will last forever

I think you did a very good job. The only recommendations that I would make are more a personal thing. I like to mount my motor and compressor on its own platform. That way, I can more easily just connect an airline to any size tank I want. I usually mount the motor and compressor outside in some kind of shed or something. Then I run a line to the radiator and then to the tank farm. This keeps the noise level away from my work space. You had a second tank I would have plumbed it up to the first tank for more volume of storage. But that's more of a personal thing based on my set up in which I have a smaller compressor. So I rely on a larger storage volume to get through large jobs. While the pump is running, we'll take a break every now and then to let the tanks fill back up. People always throw out tanks when their compressors go out. So as long as the tank itself is good, we just have to Hook up an airline and start the compressor early. Usually, with the capacity of the tank farm, we can keep up with the workflow even with a lower output compressor. It's not ideal but with free tanks readily available. For us, it just makes sense to use a tank farm and the single, smaller, more efficient compressor.

Something to add is on the intake side. Get a car muffler and a polaris sportsman air filter(or similar style). Plumb the muffler between the intake and filter. Most of the noise from a closed crankcase compressor is from the intake valves. The muffler will remove most of it.

I love air compressors that run at a lower RPM like the 1050 rpm one you purchased. It's not only the noise level that matters but also the type of sound they emit. It's a lower, punchier sound that's more pleasant to listen to. They can also last longer because they spin slower.

love the pressure test, for safety reasons he moved the compressor next to his neighbors house lol

Very impressive video. You really put a lot of work and research into it. I appreciate how you showed and analyzed the different reviews on the pump and zeroed in on how some of the bad ones were due to user error. Love your water cooling system. I basically want to replicate exactly what you did. Thanks for linking to the pulley.

My day job is designing air compressors. I expected this to be hilariously bad, but I was pleasantly surprised. A few basics were skipped over, but this isn't exactly a how to video. The water cooled aftercooler is definitely a unique idea. There should be a plate welded to the tank that says the actual rated pressure of the tank, which is usually 150-200 psi.

I just can't get enough of your channel! So many ideas to make equipment and repairs better than anything consumer-grade, but for less money. Thank you for taking the time to document what you do; it really inspires us!

Not that I've watched a ton of air compressor videos but I have watched several and this is by far the best one for anyone who is looking to build or fix a current issue. This is my first opportunity to watch your videos but after I hit the Subscribe button I know for sure I will watch them anymore. Thank you in advance for the great content that I'm sure I will continue to use
